I've got an XD in .45 acp. I handload all my ammo and just recently started loading lead bullets. This is my first experience with cast bullets. I love the way they shoot and the price aint too bad either. The first time I cleaned the gun after shooting lead it took forever to get the fouling out. The next time I shot the cast bullets (about 100rds), I followed them with about 50 rds of jacketed bullets and, viola, lead fouling gone. Really easy to clean afterwards. I've done this a couple times since with the same results. Anyone see any danger to me or my gun doing this? Is switching btw cast and jacketed bullets a bad idea?
